My son had 2 Aneurysms rupture a little over 1 year ago. They coiled both of them which left 1 Aneurysm that had not ruptured and they did not coil it because it was to small. This resulted in memory loss and numbness to his left foot. My questions he seems to get extremly tired just walking from one to room to the next is this normal after a year or is it an indication of a problem
